Measure the voltage, current and power. The PF is power/(volts x amps).

What is kilowatt of 10k at 208volts?

The formula you are looking for is kW = I x E x pf/1000 for single phase and kW = I x E x 1.73 x pf/1000 for three phase.


What is the equations to get KW of a generator?

The formulas you are looking for are, single phase kW = I x E x pf/1000. For three phase kW = I x E x 1.73 x pf/1000.


How do you calculate kwh in three phase?

In exactly the same way as you do so for a single-phase load. It's the product of the power of the load, expressed in kilowatts, and the during of operation, expressed in hours. (And the symbol of kilowatt hours is 'kW.h', not 'kwh')


Phase difference between voltage and current at resonance?

The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.


How do you convert a 0.37kw 4 pole 3 phase motor to single phase?

The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.


You have one hp three phase motor where as available power supply is only single phase how can you run this motor?

You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com


How many amps for 430kW at 208V?

Because the voltage is 208 I will assume that it is the 3 phase formula you are looking for. Amps = Kw (430) x 1000/1.73 x Volts (208) x pf. Unless you know the pf use .9 and you won't be to far off in the calculation. Same formula for single phase but don't use 1.73.


How do you calculate KVA with the help of frequency and voltage?

Assumption: F= 60Hz V= 1v is equal also to I=1amp. PF= 0.85 Single Phase: Three Phase: S = IV pf / 1000 S = 1.73 x I x V x PF/1000 = 1 x 1 x 0.85/1000 = 1.73 x 1 x 1 x 0.85 /1000 S = 0.00085KVA S = 0.0014705KVA


How do you draw phase diagram for transformer operating at load with lagging PF and leading PF?

In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.


Is the type of wiring in most homes single-phase or three-phase?

Single phase.


Single phase and three phase circuit?

Yes, there is a difference between single phase and three phase circuits.


Two phase instruments?

There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
